An industrial safety connection used to connect an industrial safety rope to prevent a worker from falling in an industrial site and a fire suppression site, and to connect and secure one end of the rope to a pipe constituting a scaffold and a specific locking member. Since the ring uses 48.6 mm in diameter for scaffolding pipes, in order to connect the industrial safety linkage to the pipe having the above-mentioned diameter, it is necessary to reduce the size of the linkage because the opening dimension must allow the pipe dimension. As a result, the cost of materials was high, and they could not stand out in the competition for external prices.

In addition, the rope used to be connected to the industrial safety linkage is based on the number of strands, so-called '8-year rope' consisting of 8 strands does not cause twisting, but in the case of '3-year rope' consisting of 3 strands Twisting occurs between the joint and the rope joint, but there is no proper twist prevention means to prevent this.

In some cases, the iron plate is pressed to make the ring body of the industrial safety connecting ring. However, in this case, the end face of the pressed steel plate is rough so that the rope is damaged by the rough surface of the steel plate. In some cases, there were a number of problems, including safety at risk.

Therefore, the present invention is to provide a new industrial safety connecting ring to eliminate the problems of the existing industrial safety connecting ring as described above,

In particular, the present invention provides a compact size of the industrial safety connection to reduce the material cost and ease of use, and to minimize the twisting of the rope to be connected, to extend the life of the rope, to minimize the safety of the safety and damage of the ultimate ultimate user The present invention has been completed in view of the technical problem of the present invention by providing an industrial safety connection that maximizes safety.
